Product Details
Fast-cutting aluminum oxide abrasive grains are resin-bonded to a durable cotton cloth backing to provide continuous cut and long life. This belt features an open coat and load-resistant coating that makes it particularly favorable for sanding soft woods. The washable backing is suitable for high production environments where the belt may need washing at intervals to remove soft wood resin or pitch buildup. Aluminum oxide mineral is a popular choice among industrial professionals due to its cut-rate, durability, and long life, making it applicable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys, and it is the most commonly used industrial abrasive. The abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure. Abrasive belts are available in various widths and lengths and are used on different belt sanding tools for multiple applications on both wood and metal. 3M offers a broad selection of belts to fit most industrial belt sanders. Wider belts are used with wide belt sanders to dimension or finish wood panels, smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts fit onto edge sanders for sanding flat, narrow surfaces such as panel edges, while narrow belts are used with portable belt sanders for sanding or blending wood pieces like cabinet doors. Belts come with various splices that join the belt ends; a film media splice achieves a secure bond with a joining film that minimizes chatter marks, ensures a smooth running belt, and produces consistent finishing results, whereas a sine wave splice is constructed of interlocking fingers that enable the splice to travel smoothly over contact wheels, reduce hinging, and provide added strength to the joint area, typically used for coarser grades and wide belts as well as on belts that are going to be washed.
